danilo, 
Entering hour 12 of being nerd-sniped by #WiFi throughput failures
I have, so far:
Manually set the house's 5 ESP32-based heat pump controllers to their lowest transmission power
Adjusted the AP’s 2.4GHz radio to use less power
Created a dedicated SSID for streaming clients at exclusively 5GHz
Removed short-range extender in the basement
Overall performance is much improved, but I still get an intermittent collapse in throughput. Going to have to pull out the #SDR next
